Hello Bruce,
Yes, there are all sorts of pregnant packages and web sites that will solve the problem in a jiffy. But LAPACK, for instance, is over 45 megabytes long.
What I am looking for is a targeted solution to the problem... a routine or set of routines that I can drop into Lady Heather with a minimum of muss and fuss that will spit out those two magic numbers.
The idea is to collect data for a while, press a key, and Heather will characterize your oscillator. I have code in there that does this if you have the active temperature control working (stabilize temperature to get osc drift rate, slew temp to get osc tempco). I would like to be able to do it for the more general case where the unit is not under temperature control.
---------------------
Try one of the Lapack derivatives such as clapack, Lapack++ etc
However you will need the optimised BLAS as well.
